The Best Things to See and Do in the Brecon Beacons National Park in Wales

Updated February 2022

The Brecon Beacons in Wales is one of the most beautiful National Parks in the UK.

The Brecon Beacons National Park was established in 1957 and covers 519 square miles. It consists of four main areas – The Black Mountain in the west, Fforest Fawr Unesco Geopark, The Central Beacons home to Pen y Fan, the highest mountain in South Wales and The Black Mountains in the east; yes, there really is a singular and plural Black Mountain area.

I had booked to stay in the Brecon Beacons for three nights and was looking forward to discovering all of its treasures. I had organised a packed 3-night travel itinerary to include all my favourite things to do; walking, discovering waterfalls, climbing mountains, visiting pretty villages and exploring ancient Welsh monuments.

I chose to stay at The Plough Inn at Rhosmaen just outside the town of Llandeilo, which is just on the outskirts of the Brecons. I did have to drive back into the national park each day for the activities we wanted to do, however with the scenery so spectacular, it was an absolute joy.

Driving from England to Wales

Driving times will always vary according to traffic and weather conditions and, of course, the dreaded roadworks that seem to always be on the route you want to use!

We left home at 10 am from Surrey in England and crossed the Severn Bridge into Wales at 2 pm, a total of 4 hours driving. From that point, it took us until around 5 pm until we reached our hotel, with stops to visit Castell Coch (a fail as we hadn’t pre-booked tickets) and at the Black Mountain Quarries (a success because it’s open to all!) So in total, from our house to our stay at The Plough Inn took 7 hours.

Keep in mind your driving times to allow for convenience stops and sightseeing stops on route. Pack snacks and water for your journey so you don’t need to stop for a meal.

Top Tip: Do you want to drive to Wales but don’t own a car? Europcar rent vehicles at reasonable prices and have good ratings.

Brecon Beacons 3-Day Itinerary including Directions

Please note that even though the driving times between locations may seem long, the scenery is stunning, so every journey is delightful.

Day One

Castell Coch

Driving for 30 miles into Wales after crossing the Severn Bridge from England will bring you to one of Wales fairytale castles. Castell Coch (meaning red castle) is a turreted Gothic revival castle built in Victorian times as an elaborate folly to showcase the wealth and imagination of its owner, the third Marquess of Bute.

Top Tip: If you want to visit Castell Coch, make sure to pre-book tickets; otherwise, like us, you may come away disappointed.

Castell Coch to Henryd Falls – 60 minutes

Henryd Falls

Also known as the waterfall used in the Batman film “The Dark Knight”, this is the tallest waterfall in South Wales with a drop of 90 feet. Henryd Falls is one of several Brecon Beacons waterfalls in the area, giving it the nickname “Waterfall Country“.

You will hear the intense thundering of the water before you see the waterfall. A bonus is that you can walk behind this waterfall which is fun but will get you very wet; bring a change of clothes! Walking down is quite slippery even with proper boots on, so make sure yours have a good grip.

If time is on your side, you can add a walk from Henryd Falls to Nant Llech across fields, taking in two smaller waterfalls on the route.

Top Tip: A free National Trust car park is by the entrance to the falls in Coelbren, SA10 9PH.

Black Mountain Quarries

Our first taste of the enormity of the Brecons was the Black Mountain Quarries which is a large area of abandoned limestone quarries. We drove towards Llangadog on the A4069 on our way to our accommodation in Llandeilo and were stunned at the landscape’s natural beauty.

A brief stop and walk near the car park allowed us to breathe in the fresh Welsh air and take in the seemingly never-ending views. This was such a great start to our trip, and I would love to return to the Black Mountains and spend longer exploring them.

Visitors can also experience red Kite feeding in Llangadog, and although we missed the time slots of 2 pm and 3 pm, it looks like a fun thing to do in the Brecon Beacons for bird-watchers, photographers and animal lovers.

Day Two

The Plough Inn to Lyn Brianne – 35 minutes.

Lyn Brianne Dam and Reservoir

Lyn Brianne dam and reservoir,  just outside Llandewi Brefi, is in a beautiful setting and is an engineering masterpiece. The drive to it through the Welsh country lanes is pretty, but there aren’t any signposts for the reservoir, so to make it easy for you, here is the postcode Llandovery SA20 0PG.

If you are lucky, you will see the dam in full force, spilling water over and down the sluice. On our visit, the water level in the reservoir wasn’t high enough, so we only got to see the hydroelectric generating station at the foot of the sluice propelling water into the air. Still very impressive and so powerful.

The reservoir is simply stunning, and a 27km walking route starts at the dam and stretches right up to the lake’s northern tip before coming back down. We walked for a few miles, but because we had a lot of other things to do in the Brecon Beacons, we didn’t venture too far. We did the short flat walk on a gravel surface, so easy to manage for most ability levels. The west side of the walk is a forestry track, and the east side is a road.

Under the reservoir, there are a couple of flooded houses. Before floods raised the water level, it was possible to walk to the Fannog farmhouse.

Top Tip: Keep a lookout for the roof of the flooded Fannog farmhouse when the water level is low.

Lyn Brianne to Abergwesyn Common –  30 minutes

Abergwesyn Common

Leaving Lyn Brianne Dam, don’t exit onto the road you arrived on, instead take the road up to your left and get ready for the most breathtaking scenery you could imagine. The road takes you around the rim of the reservoir to Abergwesyn Common. On the way, there are several car parks to enable you to admire the view back across the reservoir or go for one of several Brecon Beacon walks in this area.

Aerial view of Lyn Brianne

The 16,500-acre Abergwesyn Common is visually stunning and was bought with donations from local people and charitable funds in memory of those who have died for the United Kingdom. It is a fitting tribute to such men and women with a stream rushing through it and far-reaching views from its peaks.

Walking trails take you around the commons, rich in archaeology, from Bronze Age ritual sites to deserted medieval villages. Wherever you walk, you’re likely to come across a cairn – a stone circle – or standing stone, evidence of human activity dating back thousands of years.

We stopped and admired the views but saw others walking across the diverse and mesmerising landscape of this area, and we vowed to return and explore it ourselves.

Abergwesyn Common to Llanwrtyd Wells – 20 minutes

Llanwrtyd Wells

Gasping for a coffee, we stopped off in Llanwrtyd Wells, Britain’s smallest town. Caffi Sosban housed in a former bank (check the original vault door downstairs), was our salvation, and we sat in the small patio garden overlooking the River Irfon to enjoy our refreshments.

The town itself is home to the world bog snorkelling championships (I kid you not!) but also has a few places to eat and drink if you are looking for something more than a coffee.

Llanwrtyd Wells to Pen Y Fan – 50 minutes

Pen Y Fan

We had pondered when, if, and why we should climb Pen Y Fan – the highest mountain in South Wales and decided to go for it on our first day in the Brecon Beacons. Pen y Fan sits adjacent to Corn Du, and the twin mountain peaks are known as “Arthur’s Chair”, named after the mighty King Arthur of the sword in the stone fame. Hikers can find some of the best walks in the Brecon Beacons around this summit.

Arthurs Chair

We arrived at the Pont ar Daf car park in the early afternoon. The sun was shining, and the place was packed, but before we had time to change our minds, my trainers were on my feet (my walking boots had just fallen apart,!) and we set off to tackle this mighty mountain.

Want to know how we got on and whether this climb/walk/hike is suitable for you? Check out my post about Pen Y Fan to help you make your decision. All I can tell you is it is not as easy as the guidebooks would have you believe!

Pen y Fan and Corn Du form part of the sixteen peaks situated on The Beacons Way, a 159km walking route passing through the heart of the Brecon Beacons National Park.

Top Tip: Explore Pen Y Fan in the afternoon; it will still be busy but not as crowded as in the morning.

Day Three

The Plough Inn to Llandeilo – 5 minutes

Llandeilo is a pretty Welsh town with pastel-coloured houses and cute independent shops, and we wanted to check it out as we were only staying down the road. Unfortunately, as it was a Sunday, we found all the shops were closed, apart from the cafe, which seemed to have attracted the entire town!

Nevertheless, we had a wander down to the stone bridge that crosses the River Towy, which gave us a great vantage point to look back at the colourful terraced houses that line the main street. On a weekday, you will find shops with cute names such as The Cuckoo’s Nest and The Lighthouse, selling quality local crafts and souvenirs. And not forgetting Ginhaus Deli which sells all things gin related and you’ve guessed it some rather lovely delicatessen items.

The chic Cawdor Hotel, set in a 17th-century coaching inn, is on the high street and is a 10-minute walk from Llandeilo train station (providing regional rail services). We ate dinner here on our last night, and it was delicious. A great place to stay if you aren’t arriving by car.

Top Tip: On the way out of Llandeilo, grab a coffee at The Hangout; strangely, you will find it on an industrial estate but believe me, the coffee is excellent.

Llandeilo to Carreg Cennen Castle –  13 minutes

Carreg Cennen Castle

Romantic, mystical and downright beautiful are adjectives I would use to describe Carreg Cennen castle. Sitting 300ft above the River Cennen, these 13th-century castle ruins have 360-degree views across the Welsh countryside and, in my opinion, are one of the best places to visit on a trip to the Brecon Beacons.

The quaint gift shop is where you purchase an entry ticket – and maybe a welsh cake and a cup of tea! Then it’s off up the track leading to the castle. We loved that we arrived just as it was opening and so had the place to ourselves. The sun was shining, and the dew on the grass sparkled, bringing Carreg Cennen alive.

The castle is not very big, so you will probably only spend about 30 minutes there but should you decide to explore the surrounding countryside several walks start at the castle.

Top Tip: Carreg Cennen Castle is one of the best dark skies spots in Wales. If you want to stargaze, this is the place to do it.

Llanddeusant sheep

As you drive around the Brecons, you will notice all the sheep, and at last count (not by me!) there were 9.53 million sheep in Wales! There is even a company that offers sheep trekking days.

We passed through LLandeusant as we drove through the Black Mountains and couldn’t believe how many there were. The last time I saw this many sheep was in New Zealand! The long straight road that runs through Llanddeusant seemed to be a magnet for cyclists as we passed quite a few on our way. A lovely cycle route to take through such magnificent countryside.

Llanddeusant to Usk Reservoir –  30 minutes

Usk Reservoir

A more understated reservoir than Lyn Brianne, the 280 acre Usk Reservoir is suitable for a quick pit stop through the Brecons. It is in a remote area surrounded by forest, and a 9km loop trail allows walkers and cyclists to explore more of it via forest tracks and footpaths. The reservoir is one of the best still water trout fisheries in Wales, and visitors can fish with a permit.

Top Tip: If you have a dog with you, this is an excellent place for a dog-friendly walk.

Monmouthshire and Brecon Canal 

The Mon and Brec canal, as it’s fondly known, runs 33 miles through the Brecon Beacons. It is one of the most popular places to visit in Brecon, starting in the main town and following a course until it reaches Pontypool. Many visitors to Wales enjoy week-long boating holidays beginning at one end of the canal and finishing at the other; a leisurely way of enjoying the beautiful countryside, small villages and welcoming pubs.

Its original use was to work alongside a network of tramways and/or railroads to bring coal and iron to the main Welsh towns. These tracks are long gone, and the canal is now used for pleasure crafts rather than industrial barges. It is also a popular place to walk, which is why we decided to check it out.

The walk starts at the canal bowl beside Brecon Theatre, an excellent place to grab refreshments and use the facilities. Along the way, information boards give the visitor an insight into the history of the canal and the vital role it played in this area.

We walked for around 30 minutes and then turned back and returned. I was a little disappointed it wasn’t a quiet walk due to its proximity to the main road, but I am glad we gave it a go. In Autumn, when the leaves are changing colour, it is meant to be one of the most beautiful walks in Wales.

Top Tip: Dragonfly day cruises will take you on a scenic trip along the canal

Brecon Canal to Llangorse Lake –  15 minutes

Llangorse Lake

Llangorse Lake was high on my list of places to visit in the Brecon Beacons and, as it turned out, one of my favourites. It is the largest natural lake in South Wales and has been here since the last Ice Age.

Wondering what a crannog is? Just imagine Hagrid’s hut from Harry Potter but on its own island in the water! A crannog was an ancient lake dwelling found throughout Wales, Scotland, and Ireland built out in the water as a defensive dwelling. In addition to that, there are plenty of things to do at Llangorse Lake, including hiring rowing boats, SUP and kayaks, to name a few, and it also has the only surviving crannog in Wales.

A dedicated visitor centre tells the story of King Arthur and how he threw his fabled sword back to the “Lady of the Lake”. Local legend suggests the lake was at Llangorse.

Llangorse Lake also has a lakeside walk which is the reason for our visit. Several online maps to show you the route, but we found them hard to follow; at one point, they took us across a farm which we soon found out was not the correct way!

The Llangorse Lake walk isn’t actually a loop walk. However, it is lovely and takes you across fields, beside the lake at points and finishes at the Victorian church of St Gastyn, famous for its gothic revival architecture. Once you have spent some time at the church, retrace your steps back to the start of the walk.

Top Tip: Wear good walking boots as parts of the route can be boggy after rainfall.

Day Four

After our 3-nights in the Brecon Beacons, we checked out and started our drive to Pembrokeshire for the second leg of our holiday in Wales. We made a few stops on the way, but Talley Abbey was the last one in the Brecon Beacons.

The Plough Inn to Talley Abbey – 12 minutes.

Talley Abbey

The 12th century Talley Abbey is famed for being the only abbey in Wales for Premonstratensians monks, known as the ‘White Canons’ from the colour of their habit.

The Brecon Beacons weather was dreary on our last morning but somehow added an ethereal atmosphere to this hallowed spot. The impressive church tower stood out proud amongst the ruins, and a plan shows what the abbey would have looked like when it was in use.

Take the time to visit it on your way out of Llandeilo as it is quite a sight (especially if you like religious monuments), and should you fancy a walk; the Talley Woods are opposite with 2km and 4km trails to follow.

Leaving the sleepy village of Talley, we headed off for 7-nights in Pembrokeshire for the next part of our road-trip adventure, totally excited and looking forward to experiencing all the best things that Pembrokeshire could offer!

Talley Church


These are just a few of the things you can do in the Brecon Beacons, and after you have been once, I am sure that you will want to return again and again; I have already booked up for next year! It is a walkers paradise and one of the best places in Wales for a 3-Night Staycation.

If you love chasing waterfalls, enjoy visually stunning landscapes and want to explore the history of Wales, then this will be a perfect destination for you.

Other fun things to do in the Brecon Beacons include:

Brecon Mountain Railway

Penderyn Distillery

Four WaterFalls Trail

Wings of Wales Falconry

Alpaca Trekking

Horse Riding

National Showcase Centre for Wales

Lyn y Fan Fach Walk

Dinefwr Castle and Reserve
